Abstract (en)

[origin: EP3156609A1] A turbine nozzle (100) includes an airfoil (400) that extends in span from an inner band (200) to an outer band (300) where the inner band (200) and the outer band (300) define inner and outer flow boundaries of the turbine nozzle (100). At least one of the inner band (200) and the outer band (300) defines a plurality of cooling channels (214, 314) formed and a coolant discharge plenum (216, 316) beneath a gas side surface (218, 318) of the corresponding inner band (200) or outer band (300) that is in fluid communication with the cooling channels (214, 314). The coolant discharge plenum (216, 316) is formed within the inner band (200) or the outer band (300) downstream from the cooling channels (214, 314) and upstream from a plurality of coolant discharge ports (226, 326).
